Daniel Dai commented on PIG-2586: --------------------------------- There is a partial patch in https://github.com/manuranga/svg-graph. It has not linked to Pig yet. > A better plan/data flow visualizer > ---------------------------------- > > Key: PIG-2586 > URL: https://issues.apache.org/jira/browse/PIG-2586 > Project: Pig > Issue Type: Improvement > Components: impl > Reporter: Daniel Dai > Labels: gsoc2012 > > Pig supports a dot graph style plan to visualize the > logical/physical/mapreduce plan (explain with -dot option, see > http://ofps.oreilly.com/titles/9781449302641/developing_and_testing.html). > However, dot graph takes extra step to generate the plan graph and the > quality of the output is not good. It's better we can implement a better > visualizer for Pig. It should: > 1. show operator type and alias > 2. turn on/off output schema > 3. dive into foreach inner plan on demand > 4. provide a way to show operator source code, eg, tooltip of an operator > (plan don't currently have this information, but you can assume this is in > place) > 5. besides visualize logical/physical/mapreduce plan, visualize the script > itself is also useful > 6. may rely on some java graphic library such as Swing > This is a candidate project for Google summer of code 2012.
